Mr Schumacher dressed up for parties and made sure his chassis always had odd numbers, team and technical director Ross Brawn revealed. Speaking on Formula 1 podcast Beyond the Grid, Mr Brawn said the record-breaking racing driver loved fancy dress.
Mr Brawn said: “He loved to dress up, he was always dressed up, fine outfits were custom at his parties.”
And the Formula 1 legend’s former colleague described how Mr Schumacher refused to have even numbers on his chassis.
Mr Brawn said: “He was totally superstitious when it came to odd numbers, his chassis always had odd numbers.”
He added that Mr Schumacher – who won seven world titles – tried to keep out of the spotlight.
Mr Brawn said: “He was always happy to be shielded.
“That’s why he liked the US so much – because nobody knew him there – he found the privacy and peace he lacked in Europe.”
It comes after Mr Schumacher’s wife Corinna Schumacher released a rare statement on Wednesday to mark the racing driver’s 50th birthday.
She said: “We are pleased and wholeheartedly thank you for celebrating Michael’s 50th birthday with him and with us.
“You can be sure that he is in good hands and we are doing everything humanly possible to help him.
“Please understand if we follow Michael’s wishes and leave as sensitive a topic as health, as ever, in privacy.
“At the same time, we thank you very much for your friendship and wish you a happy and healthy year in 2019.”
Mrs Schumacher added that the family are proud of his achievements.
She said: “Michael can be proud of what he has achieved, and so are we! That’s why we remember his successes with the Michael Schumacher Private Collection Exhibition in Cologne, by publishing memories in social media and by continuing his charitable work through the Keep Fighting Foundation.
“We want to remember and celebrate his victories, his records and jubilation.”
Little has been known about Mr Schumacher’s health since his devastating French skiing accident in 2013.
He was placed in a medically induced coma for six months before leaving hospital to continue his recovery at home in Switzerland.
